python-keystoneclient missing expiration check in PKI token validation
python-keystoneclient before 0.2.4, as used in OpenStack Keystone (Folsom), does not properly check expiry for PKI tokens, which allows remote authenticated users to (1) retain use of a token after it has expired, or (2) use a revoked token once it expires.
